1. Report Industry Investment Rating - No relevant information was found. 2. Core View of the Report - The market for ethylene glycol is currently in a weak state, with prices fluctuating at a low level and overall trading being rather stagnant. The downstream polyester production and sales are generally light, and the reduction in production scale is gradually increasing. At the same time, the supply is expected to increase as multiple ethylene glycol units complete maintenance. The cost support is weakening due to the easing of geopolitical conflicts and the weakening of crude oil trends. Overall, the ethylene glycol market is expected to remain weak in the short term [2]. 3.
